Small Intestinal Crypt of Lieberkühn.

You selected: undifferentiated crypt stem cell

The epithelial crypt stem cells give rise to all epithelial cell lineages. These lineages include the villus-associated absorptive enterocytes, mucin-secreting goblet cells, enteroendocrine cells, and the crypt-associated Paneth cells. Committed precursor cells are believed to arise from a single multi-potent stem cell. Differentiation of the four primary cell types is completed at the crypt-villus junction. Villus associated cells continue their migration along the villus surface. These cells undergo apoptosis near the villus tip and are subsequently lost after 3-5 days in the mouse.
